The Norweigan royal was stunning in a pastel aqua blue tiered dress designed by Valentino, the same fashion house that created the bride's wedding dress. Topping off the look was an amethyst tiara.

Princess Tatiana of Greece had chosen the same pale colour as Mette-Marit, wearing a gown that featured a strapless bustier and ruched detailing. She added sparkle to the outfit with drop diamond earrings and the Antique Corsage, which has been passed through the hands of Queens from three different countries.

Pastels, in fact, seemed to be the order of the day, falling in line with the theme of the wedding, summer meadows. The colour scheme for the decorations was light green, white and pink, using beech leaves, cow parsley, pink and white peonies, white lilacs, foxgloves, delphiniums and lilies of the valley.

Princess Martha-Louise of Norway also stuck to the theme, opting for a satin lilac number with embroidered embellishments. She accessorised with the same tiara that she wore for her wedding day.

Princess Charlene of Monaco, who attended the ceremony without her husband Prince Albert, had chosen a similar hue. The statuesque blonde wore a mauve strapless ruched dress with peplum detailing. A gauze shawl kept her shoulders warm.
